G'day keralaqueen234,

Welcome to the monastery.

You showed a set of requirements in your initial post (files: currentlog.log, currentlog_2010.log and currentlog_2011.log). You didn't follow the advice given by hdb (using currentlog*.log instead of currentlog_*.log) and seemed surprised it didn't work. Further on, you changed your requirements showing a completely different set of filenames to match: "i have files with names currentlog.log,currentlog123.log,currentlog233.log,detail.txt,see.txt" [sic].

Any changes you make to requirements in your original posting (OP) should be clearly shown by adding an Update section to your OP. You should fix up your OP now.

This appears to be fast becoming an Off Topic thread with the problem being your lack of knowledge of your operating system rather than anything to do with Perl.

Assuming nothing else has changed between reading this thread and posting this response, it would appear that the pattern you want is: currentlog?*.log

$ ls -1
currentlog.log
currentlog123.log
currentlog233.log
currentlog_2010.log
currentlog_2011.log
detail.txt
see.txt

$ ls -1 currentlog?*.log
currentlog123.log
currentlog233.log
currentlog_2010.log
currentlog_2011.log

$ perl -E 'say for glob "currentlog?*.log"'
currentlog123.log
currentlog233.log
currentlog_2010.log
currentlog_2011.log
